Abu Shurayh al-Khuza’i reported that the Prophet, may Allah bless him and grant him peace, said, “Anyone who believes in Allah and the Last Day should be good to his neighbours. Anyone who believes in Allah and the Last Day should be generous to his guest. Anyone who believes in Allah and the Last Day should be say what is good or be silent.”
حَدَّثَنَا صَدَقَةُ، قَالَ‏:‏ أَخْبَرَنَا ابْنُ عُيَيْنَةَ، عَنْ عَمْرٍو، عَنْ نَافِعِ بْنِ جُبَيْرٍ، عَنْ أَبِي شُرَيْحٍ الْخُزَاعِيِّ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ‏:‏ مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ فَلْيُحْسِنْ إِلَى جَارِهِ، وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ فَلْيُكْرِمْ ضَيْفَهُ، وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ فَلْيَقُلْ خَيْرًا أَوْ لِيَصْمُتْ‏.‏
